(54)	Dual pressure sensor apparatus

(57) A dual pressure sensor apparatus (10) configured for attachment to a manifold (22) includes a molded plastic housing (12) with a body portion (20) featuring an upper cavity (40), a measurement port (24), and a lower cavity (42) closed by the manifold (22). First and second pressure sensor modules (16, 14) are mounted in first and second wells (50, 48) formed in the upper cavity (40), and electrically coupled to a set of leadframe terminals (46a, 46b, 46c, 46d) disposed in the upper cavity (40). An opening (54) in the first well (50) couples the first pressure sensor module (16) to the measurement port (24), and an opening (52) in the second well (48) couples the second pressure sensor module (14) to the lower cavity (42). The measurement port (24) sealingly extends through an opening (26) in the manifold (22) so that the first pressure sensor module (16) measures pressure in the manifold (22), and the body portion walls (20a, 20b) bounding the lower cavity (42) are notched (64, 66) so that the second pressure sensor module (14) measures atmospheric or barometric pressure outside the manifold (22).
